A sample containing 3.50 moles of N2 and 7.50 mol of H2 are placed in a reaction vessel and brought to equilibrium at 20.0 bar and 750. K in the reaction 1/2 N2(g) + 3/2 H2(g) NH3(g). a. Calculate Kp at this temperature. b. Would an increase or decrease in temperature lead to the production of more ammonia c. List two other things you could alter experimentally to increase the amount of ammonia (note: don't use the same effect and just change chemicals)
Consider the reaction with the rate law, Rate = k[BrO3-][Br-][H+]2 By what factor does the rate change if the concentration of BrO3- is doubled and that of Br- is doubled? Just put in the number as a whole number or fraction.
